Autor: Said A. Ibrahim, Aly A. Abdel-Hafez, Mostafa K. Rabia, S. A. El-Gyar

Publikováno v: Collection of Czechoslovak Chemical Communications. 59:1800-1808

The Co(II), Ni(II), Cu(II) and Zn(II) complexes with 8-hydroxyquinoline-5-sulfonylhydrazone are described. It has been found that the ligand can coordinate to metal ion as a monobasic bidentate chelating agent and it can form di- and trinuclear compl
